. ROPE-MEASURING DEVICE.

- Specification of Letters Patent.

Patented Dec. an, 1918.

Application filed May 6, 1918. Serial No. 232,807.

To all whom, it may concern:

Be it known that I, NORMAN A. Oms- HoLM, a citizen of the United States, residing at Brawley, in the county of Imperial and State of California, have invented new and useful Improvements in Rope-Measuring Devices, of which the following is a specification.

My object is to make a rope measuring device, and my invention consists of the novel features herein shown, described and claimed.

Figure 1 is a fragmentary top lan view of-a rope measuring device embo ying the principles of my invention, as seen looking in the direction indicated by the arrows 1 in Figs. 2 and 3.

Fig. 2 is a vertical cross section on the lines 22 of Figs. 1 and 3.

Fig. 3 is a rear elevation as indicated by the arrows 3 in Figs. 1 and 2, parts being broken away and shown in section.

A coil of rope 1 is mounted upon a spool 2 and the spool 2 is mounted upon a spindle 3 mounted in supporting brackets 4. A measuring device 5 is mounted in front of the coil 1. A base bar 6 is bolted to a base board 7 upon which base board the brackets 4 are supported. The side bars 8 and 9 extend upwardly from the ends of the bar 6. A top bar 10 connects the upper ends of the bars 8 and 9.

An operating shaft 11 is rotatably mounted in the bearings 12 and 13 in the side bars 8 and 9. A grooved measuring pulley 14 is fixed upon the shaft 11 by a set screw 15, so that theshaft will rotate with the pulley. Forks 16 and 17 are mounted at the sides of the pulley 14 straddle of the shaft 11, the upper ends of the forks being connected by a head 18. Bearings 19 extend downwardly from the head 18 and a pressure roller 20 is mounted between the bearings in line with a groove 21 in the pulley l4.

A stem 22 extends upwardly from the head 18 through the bar 10. A spring 23 is mounted upon the stem 22 between the bar 10 and the head 18, the tension of the spring being exerted to press the roller 20 against the rope 1. A handle 24 is fixed upon the upper end of the stem. 22'for raising the roller 20, so that the rope may be passed under the roller 20 over the pulley 14.

A bracket 25 extends from the inner face of the side bar 8. A shaft 26 is rotatably and vertically mounted in the bracket 25 and the top bar 10. A pin wheel 27 is fixed upon the lower end of the shaft 26 and a pin 28 is fixed in the shaft 11, so that every time the rope I is drawn over the pulley 14 to make a revolution of the pulley the shaft 11 will be revolved .and pin 28 into engagement with the 27 to move the pin wheel one step.

A hand 29 is frictionally mounted upon the upper end of the shaft 26 like a clock hand, so that the hand will rotate with the shaft 26, and so that the hand may be manually engaged and rotated without rotating the shaft as required to set the hand forwardly or backwardly. A graduated dial 30 is formed upon the upper face of the bar 10 concentric to the shaft 26, a pointer 31 upon the hand moving close to the graduations.

In the practical operation the rope 1 may be cut at a point in line with the front edge 32 of the board 7 and the pointer 31 may carry the pin wheel be set back to the graduation marked 1.

lhen if the rope is pulled over the pulley 14 the pointer 31 will move one graduation for each revolution of the pulley 14, and the pulley 14 should be, say, one foot in circumference upon its periphery, so that each point in the dial will indicate that a foot of rope has passed over the pulley. Then by pulling the rope the operator can keep track of the measurement of the rope by referring to the dial and pointer. It is obvious that. the device might be made to measure in yards instead of feet. After a sale has been made the hand 29 may be'moved backwardly or feet they wapt but they do not know how many pounds they want, and it has usually been necessary to measure the rope with the yard-stick to get the desired number of feet and then to weigh the rope to get the price. It is my intention to figure the price by the foot or yard instead of by the pound.v Then it is only necessary to cut ofi so many feet or yards and figure the price per foot or yard. I

Where the rope is not mounted on a reel it may be 'drawn from the original bale and in order to guide the rope from the bale to the pulley 14 I provide an arm 33 extending messes high points of the flanges of the pulley so as to effectually uide the rope 1 into the groove of the pul ey.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. A rope measuring device comprising a base bar adapted to be rigidly mounted, side bars extending upwardly from the ends of the base bar, a top bar connecting the upper ends of the side bars, an operating shaft rotatably mounted in the side bars, a grooved measuring pulley fixed upon the shaft, forks mounted at the sides of the pulley and straddling the shaft, a head connecting the upper ends of the forks, a pressure roller carried by the head and adapted to engage a rope and press the rope against. the pulley, a stem extending upwardly from the head through the top bar, a spring mounted upon the stem between the top bar and the head, and means operated by the rotation of the shaft for indicating the length of the rope which passes over the pulley.

2. A rope measuring device comprising a base bar adapted to? be rigidly mounted, side bars extending upwardly from the ends of the base bar, a top bar connecting the upper ends of the side bars, an operating shaft rotatably mounted in the side bars, a grooved measuring pulley fixed upon the shaft, forks mounted at the sides of the pulley and straddling the shaft, a head connecting the upper ends of the forks, a pressure roller carried by the head and adapted to engage a rope and press the rope against the pulley, a stem extending upwardly from the head through the top bar, a spring mounted upon the stem between thetop bar and. the head, and means operated by the rotation of the shaft for indicating the length of the rope which passes over the pulley and comprising a pin carried by the shaft, a pin wheel in position to be engaged by the pin and rotated step by step,a second shaft fixed to the pin wheel and extending upwardly through the top bar, a hand frictionally mounted upon the upper end of the second shaft, and a dial upon the top bar-in operative relation to the hand.

In testimony whereof I have signed my name to this specification.
